SASH-HOLDER.

SPECIFICATION forming part of Letters Patent No. 278,439, dated May 29,1883.

Application filed March 6, 1883. (ModeL) To all whom z'tmay concern Beit known that I, SAMUEL LEAR, a citizen ot' the United States,residingat Pottsville, in the county of Schuylkill and State of Pennsylvania,have invented a new and useful Improvement in Sash Lo'cks, of which thefollowing is a specification.

I My invention relates to improvements in devices for lockingwindow-sashes; and my oh- 1o ject-s are to providea means for holdingthe sash in any desired position, and to keep the sash from shaking orrattling. I attain these objects by use of the mechanism illustrated inp the accompanying drawings, in which- Figure 1 is a full view of mysash-lock as applied to a window-sash. Fig.2 is a top view, havingthe'top cut away to show its arrangement of parts and construction; andFig. 3 is a front edge view, having a part cut away to show the devicefor securing immovably the whole device.

Similar letters refer to similar parts in all the views. a

To construct my device I take the plate B, having the flange B and thelugor stop B all combined in one piece, andsecure it to the sash bymeans of a screwor any suitable fastening. In the case A, I adjust anelasticsubup, the elastic substanceX holding firmly and yet preventingthe marring or destruction of the window-frame. ,By pressing on thelever O the case A is moved, the screw D acting as a pivot, thusreleasing the sash-lock from en- I gaging with the wind0w-frame andallowing the sash to be either raised or lowered at will.

As soon as the hand is removed from thelever G the spring S acts andforces the case A back I against the window-frame. To further insure thelocking of the sash, I provide a supplemental fastening in the shape ofa small bolt device,in which E is the bolt, K a bolt-hole .in the plateB, L a spring to force the bolt shot into the hole K in the plate B thesashlock is sofastened'that it cannot be moved. This supplementalfastening I place on the lower left-hand corner of the case A, as shown.

It does not fasten the sash, but is intended to 3 f fasten togetherthecase A and the base-plate B, so that the sash-lock remains firm andcannot be operated until the fastening is released. The lug B is used.as a stop to prevent the device from being wedged too tightly againstthe window-frame.

My devicemay be used either with or without the supplemental fasteningdevice.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. The within-describedsash-lock, consisting of the stationary plate B,having flanged side B and lug or stop B in combination with the case A,having the lever (J and elastic substance X, the spring S, held behindflange B and upper flange of A,a.nd the screw D, asshown and set forth.

2. In the within -described sashlock, the combination of the case A,having lever U and elastic substance X, the plate B, having l'ug B andflanged side B the spring S, v and the screw D, with the supplementalfastening-bolt, all combined and arranged as shown and set forth.
